The disintegration rates of 35S and 14C were evaluated from the liquid scintillation spectra by the modified integral counting method. The disintegration rates thus obtained sufficiently supported the applicability of this method to the radioactivity measurement by liquid scintillation counting without using quenched standards. Discussion was also given concerning the measurement procedures involving the modified integral counting method., Article, 富山大学水素同位体科学研究センター研究報告, 33巻, 2014.06.30, pp.53-62}, pages = {53--62}, title = {積分法を用いた35Sの液体シンチレーションカウンタによる放射能測定}, volume = {33}, year = {2014} }
